  1. *p < .05, **p < .01, ***p < .001 based on Tukey post-hoc analysis. Effect sizes are designated as small (.20), medium (.50), and large (.80). Effect sizes represent the magnitude in the differences between the Fibromyalgia and Healthy Children samples only. α = Cronbach internal consistency reliability coefficient alpha. Healthy sample completed the Acute Version (7-day recall) of the PedsQL™ Multidimensional Fatigue Scale. Sample size for the Rheumatology Module Pain and Hurt Scale for Child Self-Report for Fibromyalgia sample equals 57 and for Rheumatology sample equals 150. Sample size for the Rheumatology Module Pain and Hurt Scale for Parent Proxy-Report for Fibromyalgia sample equals 57 and for Rheumatology sample equals 126. NA = not applicable.
